Answer:

B and D

Step-by-step explanation:

a is right because there are numbers that exist that are larger than five and smaller than 9

c is right because again, there are numbers that exist that are larger than -3 and smaller than 7.

b cannot be right because there are no numbers that can be larger than 9 that are also smaller than 5

d also cannot be right because there are no numbers that are less than -5 that are also more than -3.

The sum of one-fifth of a number and two is five
Veseljchak [2.6K]

Answer:

15

Step-by-step explanation:

Let us first write an equation where the unknown number is represented with variable x. <em>The sum of a fifth of x and two is five:</em>

\frac{1}{5} x+2=5

Great! Let's solve for x by isolating the variable.

\frac{1}{5}x=3\\x=15

<u>Therefore, the unknown number is 15.</u>

<u />

Use Cramers Rule to solve the system <br> 2x - 3y = 11<br> -6x + 8y = 34
Nastasia [14]

Step-by-step explanation:

given :

2x - 3y = 11

-6x + 8y = 34

find : the solutions of the system by using Cramers Rule.

solutions:

in the matrix 2x2 form =>

[ 2 -3] [x] [11]

=

[-6 8] [ y] [34]

D =

| 2 -3 |

|-6 8 |

= 8×2 - (-3) (-6)

= 16-18 = -2

Dx = | 11 -3 |

| 34 8 |

= 11×8 - (-3) (34)

= 88 + 102

= 190

Dy = | 2 11 |

|-6 34 |

= 2×34 - (-6) (11)

= 68 + 66

= 134

x = Dx/D = 190/-2 = -95

y = Dy/D = 134/-2 = -67

the solutions = {-95, -67}
